電力士電能質(zhì)量分析儀HDPQ®GuideThe Dranetz HDPQ Guide and Dranetz HDPQ Guide SP are the exact same instrument, but are in different enclosures. The Dranetz HDPQ Guide is a true hand-held portable instrument with a built in 7″, tablet-like touch LCD display. The Dranetz HDPQ Guide SP has the same measurement and communications capabilities, but is housed in an IP65 enclosure without an LCD display. The IP65 enclosure of the Dranetz HDPQ Guide SP greatly expands the applications of the Dranetz HDPQ Guide into outdoor and harsh environments, along with other applications where an LCD display is undesirable.
